How can I compute the surface area of a cylinder?
To compute the surface area of a cylinder, you need to find the sum of the areas of its curved surface and its top and bottom surfaces. The curved surface area of a cylinder is given by the formula surface area = 2πrh, where r is the radius of the cylinder and h and h is the height of the cylinder. To find the surface area of the top and bottom surfaces of the cylinder, you need to find the area of each surface and then add them together. The area of the top surface is given by the formula area = πr2, where r is the radius The area of the bottom surface is also given by the formula area = πr2. Therefore, the surface area of the cylinder is given by the formula surface area = 2πrh + πr2 + πr2 = 2πrh + 2πr2.
